The method used to estimate ideal points for contributors is described
in "Ideology and Interests in the Political Marketplace" (Bonica 2012). 
The dataset of contributor records that was used to
recover estimates is downloaded from the Federal Election Commissions
Website (http://data.fec.gov). Variables compiled in other datasets are 
indicated in paratheses before the variable name. Please attribute
credit accordingly.  

(PR) The DW-NOMINATE scores are from by Poole and Rosenthal (2007) and are
made available at voteview.com. 

(SW) Committee membership data is from Charles Stewart and Jonathan Woon at:
http://web.mit.edu/17.251/www/data_page.html. Their preferred citation
is, "Charles Stewart III and Jonathan Woon.  Congressional Committee
Assignments, 103rd to 111th Congresses, 1993--2009"
